Commit 1: improvement(client): core-utils imports explicit paths
Make core-utils source (not test) ECMAScript compilable
Change util scripts to be explicitly CommonJS

This allows core-utils package to use "type": "module" by only changing build settings.

Commit 2: feat(client): core-utils as ESM package
with CommonJS secondary support

Make core-utils source (not test) ECMAScript compilable
Change util scripts to be explicitly CommonJS

This allows core-utils package to use "type": "module" by only changing build settings.

I don't understand the fluid build system well enough. This task does not get run if I don't invoke it explicitly.

…re, runtime, Loader in versioned tests (microsoft#20650)

An extraction from microsoft#20621

Reason for changes
These tests explode when I change interface between DDS & DataStore

Description
These tests are not written correctly. They mix arbitrary version of DDS with the latest version of FluidDataStoreRuntime (through TestFluidObjectFactory). We never supported such mixes - version of DDS has to match version or data store!

Using matching TestFluidObjectFactory is easy, but then we start running into somewhat similar problem of mixing FluidDataStoreRuntime & ContainerRuntime. We support only N/N-1 mixes here, and nothing more. So we have to use the version provided by test framework, thus you see some dance above CodeLoader to get right factory.

And while we are at it, it would be great for the test to use Loader version provided by test framework, not latest version.
This breaks for old versions as the way test is written it works only for latest structure of the document. Previously test framework was running a ton of combos, but most of them were actually the same, as even when it was supplied different versions of loader, we were using only latest version of loader. So, the right fix here - use loader version provided by framework but skip all the tests that use old version of the loader, thus getting same result, but with fewer iterations (and faster tests).

As part of fixing it, use proper back-compat compatible ways to get to entry points at loader & runtime layers.

## Description

This makes 3 changes to Tree.is:
1. calling Tree.is(node, SchemaNotUsedInTreeSchema) is no longer an
error. This undocumented edge case could have been problematic, and is
inconsistent since it would not fire if node was not a TreeNode.
2. Tree.is now takes in ImplicitAllowedTypes, making cases like
Tree.is(x, [schema.number, schema.string]) valid. THis is more
performant and more concise then doing two separate checks and ORing
them together. This also allows checking a node against an
ImplicitAllowedTypes pulled from a FieldSchema which could be handy for
some generic code.
3. The implementation of Tree.schema and Tree.is have been rewritten to
not rely on flex-schema as much, and fast path non-TreeNode inputs. This
should make it more maintainable and more performant.


Interestingly `#2` above is the only case that couldn't be covered by
`instanceof` (assuming TypeScript 5.3): we could make `instanceof` do
all narrowing currently done with Tree.is, except for this new case. The
presence of this case thus seems to motivate keeping `Tree.is` if for no
reason other than it can support this additional pattern which
`instancof` cannot.
